rules: 1. make sure that the monster fits the key and tempo 2. sounds are in the backdrop so add them there 3. no ai 4. the monster should be fanmade, official or from someone else but if youre using someone else's monster then credit the person who made it 5. here's what you need to use for the monster's sound: Beepbox/Ultrabox Online Sequencer Soundtrap FL Studio Garageband Ableton and you shouldnt use scratch sounds and no sounds from the music extenxion because thats a thing of the past
note as well: remix the project (haha you already know lol)
